Okay, kiddo, have you ever had chicken or turkey at Thanksgiving? Well, sometimes people make a fancy dish with those meats called galantine.
Galantine is made by taking the meat off of the bones and then mixing it with different things like herbs, seasonings, and sometimes even other meats. Then, they roll the mixture up really tightly and tie it with string to keep it together.
After that, it's cooked, and then chilled before being served. And ta-da! You have a fancy dish that looks really cool when you slice it and can be served with different sauces or sides.
